Kim and Khloe Kardashian shot a Quick Trim commercial in Miami the other day. Kim blogged: “The beach was so beautiful and we were having such a great time enjoying the sand and sun. I can’t wait to show you guys this commercial. I Twittered one of these pics last week, but I wanted to share the rest with you guys here. I really feel like I have reached my fitness goal and now I am toned, fit and at a healthy weight and I just need to keep it up!”
